IMPROVEMENT IN HOLDBACKS FOR VEHICLES.

Specification forming part of Letters Patent No. 192,422, dated June 26,1877 application filed May 26, 1877.

To all whom z't may concern Be it known that I, CHARLES J. ELLs- WORTH,of Fisherville, of the county of Merrimack, of the State of NewHampshire, have invented an Improved Holdback for the Thills ofWheel-Carriages; and do hereby declare the same to be described in thefollowing specification and represented in the accompanying drawings, ofwhich Figure 1 is a side elevation, Fig. 2 a top view, and Fig. 3 alongitudinal section, of it. Fig. 4 is a transverse section takenthrough the groove of the standard.

In such drawings, A denotes a standard or post, hooked or curved at itsupper part and grooved on its top, in manner as shown. This standard hasa screw, a, projecting down from it, to screw into a shaft and aid infastening the holdback thereto.

There also extends back from the standard, at a right angle to it, anarm or projection, 11, having at its rear end a hole, 0, for receiving ascrew for confining the arm to a shaft. 7

The said arm is chambered, as represented at h, to receive a helicalspring, d, arranged in it, as shown.

Furthermore, there is hinged to the arm a bent lever or tongue, B, whoseshorter arm 6 extends down into the spring-chamber and against one endof the spring. The longer arm of such lever is bent upward, over, andrests within the groove of the standard, and extends down in front ofthe standard, in manner as shown. a

In this holdback the spring is not on the outside of the standard, butis confined in a chamber, where it is protected from injury or loss, andthe lever or tongue, instead of being hinged to the standard, is hingedto the arm, and is supported both laterally and longitudinally bythe-standard and the arm.

I do not claim in a holdback the tongue hingedto the top of the standardand provided with a spring to extend over both. With my holdback thereis little or no chance for the harness-breeching becoming accidentallydisengaged from the standard, and besides, should the whiffletree becomebroken, the holdback enables the horse to clear himself with greatfacility from the shaft.

Nor do I claim a holdback constructed as shown in the United StatesPatent No. 48,415, wherein the post or standard is inclined at an obtuseangle to its base, where the spring and post are inclined at obtuseangles to the base.

In my holdback the standard or breechingstrap bearing part thereof isupright, or in line with the screw 0., and the spring-chamber and springare arranged at a right angle to the said screw and in the arm Z),whereby I am enabled to use a very long spring, and to apply it to goodadvantage to the tongue; therefore' I claim- The improved holdback,constructed substantially as described-viz., with the vertical hookedand grooved standard A, provided with the spring-chamber h and spring61, arranged in its arm b at a right angle to the fastening-screw athereof, and having the tongue B pivoted to the arm, and extended intothe said chamber and against the end of the spring, so as, when down, torest in the groove of the head of the standard, all as represented.
